Bolivar Trask is a fictional character appearing in Marvel Comics, primarily associated with the X-Men.

He is a brilliant but prejudiced scientist and military contractor who believes that mutants pose an existential threat to humanity. Driven by this fear, Trask dedicates his life to developing technology to combat the perceived mutant menace.

Trask's most notable creation is the Sentinel program. These giant, robotic hunters are specifically designed to identify, capture, or neutralize mutants, with each generation becoming more sophisticated and dangerous.

While initially portrayed as motivated by genuine concern, Trask's actions often lead to unintended consequences, fueling mutant-human conflict and contributing to the very future he fears. He sometimes exhibits regret over his creations, but ultimately remains dedicated to his anti-mutant cause.

His legacy extends far beyond his own lifetime, as the Sentinels continue to be a major threat in the Marvel universe long after his death, showcasing the lasting impact of his fear-driven inventions.
